OF PHILADELPHIA, PENNSYLVANIA- FINGER-BIKES.

Application filed November To allwhom itmwyconcern:

Be it known that I, PAUL E. Hnon, a citizen of the United States residing at Phil- Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Jewelers Forming and Clamping Devices for Finger-Rings, of which'the following is a specification.

The invention relates to jewelry and has for anobje'ct to provide a combined base forming, clamping and holding device for use in securing articles of jewelry such as finger rings and the like in position to be operate upon.

The invention comprehends among other features the provlsion of a simple device which in the mounting of a ring 1n position to be operated upon, molds the usual base substance such as shellac into the desire shape so that upon thehardening of the shellac and its subsequent use with my device, the ring will be conveniently held in position to be operated u on and can be uickly' and oonvemently ajusted or position'ed at various an les to the operator, permitting him to e ciently carry on suc mounting or repair work as may be necessa on the article of jewelry.

n the further disclosure of the invention, reference is to be had to the accompanying drawings oonstitutin a part of this specifi cation in which simi ar characters of reference denote corresponding parts in all the views, and in wh1eh,--

Fig'u'1'e 1 is a perspective view of the device;

Fig. 2 is a vertical longitudinal sectional view taken through the device showing a ring mounted therein, and

ig. 3 is a horizontal sectional view taken on the line 3-3 in Fig. 2.

Fig; 4 is a fra entary side elevation of a sli htljy modifie form. fer-rin more'particularly to the views I provide a body 10 havin a portion thereof formed to provide a suitab e handle or holder 11 with an upper part of the body 10 provided w'ithaeut away portion 12 and an extension forming a jaw 13, this jaw being preferably termed a stationary aw. The numeral 14 indicates a movable aw which is adapted to be disposed in opposed relation to the stationary jaw as shown, to be moved backwardly and forwardly in the cut-away portion thereon, a clamping memher or screw 15 being provided to pass Specification of Letters Patent.

through the movable jaw 14 and extend into the stationary jaw 13 so that upon actuatmg said screw, the movable jaw will be moved toward or away from thestationary aw. The jaws are maintained in substantially paral el relation by suitable gnidepins 16 which are arranged to pro' ct from the face of the stationary jaw an loosely pass throu h openings or cross passages 17 'inthe mova le jaw and an adjusting screw 18 is provided, the latter being threaded in the movable jaw and havin its inner end adapted to abut against the ace of the stationary jaw, said latter mentioned screw being vided for purposes of fine adjustment of the movable jaw relative to the stationary jaw or the parts that may beclamped; in and between the jaws.

The face of the stationary jaw is rovided with a depression or recess '19 \whi :is of a hexagonal configuration and similarly the movable jaw 14 has a depression or recess 20 of a s milar nature and in immediate opposed relation to the recess 19, it being of course understood that these recesses may be of either of hexagonal or octagonal formation. The numeral 21 indicates a finger rim and the numeral 22, the plastic base, sai base consisting of aquantity of shellac which is preferwb y first heated and then ressed within the confines of the band of t e ring after which this base carrying the ring is arranged between the jaws 13, 14, and the movable jaw is actuated to bring about a clamping o oration causing the soft and pliable shel ac to have portions thereof pressed into the recesses 19, 20 and assume the configuration of the recesses so that when the shellac hardens the body of the shellac will be formed with opposed exagonalknobs 24, 24, brought about y the pressing of the shellac into the recesses 19 20, res ectively. The ring will now be held secure y by the igase whlch in turn is secured between and 3' held rigidly upon the base, the base in turn will be held from turning by reason of the hexagonal knobs fitting into the haze nal recesses. The operator now holds the evice 1n one hand by firmly grasping the handle or holder 11 and then with the other hand, he manipulates the tool or tools with which he operates upon the ring.

By having the recesses 19, 20 of a hexagonal configuration and consequently having the formed knobs of a similar co gura- .100 the clamps and of course the ring being tion, the operator when he finishes working on the ring from one angle can unclamp the base and then position the same at a different angle, reclamping the knobs in the recesses thus permitting the operator to safely work upon the ring from different angles while holding the device substantially in the same position in the hand, thus obviating the usual danger of the tool slipping on the delicate mountings of finger rings and which ordinarily is due to the insecure clamping of the rings in working position and ofttimes results in great damage to valuable stones and settings.

By reference to F ig. 4 it will be seen that instead of having the recesses 19, 20, formed in the body portions of the stationary and movable jaws 13, 14, I may face the jaws with plates 13, 14,, the plates having cut out portions 19, 20, which will form recesses.

It should also be noted that although I mention shellac as the material employed in forming the base, I may also employ any suitable form of cement or other material which when heated will become plastic so that it can beworked into a desired shape or configuration which will be maintained upon the subsequent hardening of the material. I

From the foregoing description it will be seen that the devicedescribed consists of few and simple parts; that the same is not merely a holder for holding a ring in position to be worked upon, but that it also constitutes a means for forming a base, which in turn supports and carries a ring and it will be clearly understood that although in the drawings and this specification, I have described a particular form of my article, that various slight. changes may be made without departing from the spirit of the invention, thescepe of which isdefined in the appended claims;

wing-described my'invention, I claim,

1. device of the character described comprisingaiholfder formed as a clamping deviceincludingjaws, the jaws being formed in "their confronting, faces with angular sockets, in combinationwith a jewelry holdinglmeans formed-as a base of plastic material within-whichthe jewelry is embedded, the base being initially compressed between theja'ws wherebyto force the base into the sockets. v w

2." device for forming a plastic base for jewelry and for clamping and supporting the base, comprising a holder, a jaw on the 3. In a device for forming a plastic base i for supporting jewelry and for clamping the base, a plurality of jaws, each having a flat face provided with a recess of a hexagonal configuration and means for moving said jaws into and out of clamping positions, the plastic base carrying the jewelry being adapted for interposition between the jaws to be clamped thereby and force portions of the material thereof into the recesses to form hexagonal knobs corresponding with the recesses, securing said base thereby against movement relative to said jaws when the same are arranged in clamping relation with the base and thereby holding said jewelry in position to-be operated upon.

device for forming a plastic base for. jewelry for the latter, to adjustably mounted, comprising clamping. members and sockets associated with said clamping members and having angular surfaces for the reception of portions of the plastic base to mold the latter and form similar angular surfaces thereon so that the jewelry carried by the plastic base, when the latter subsequently bar-dens can be held by said clamping members and adjusted at various angles thereto.

5. A device of the character described comprising a holder formed as a clamping device including jaws formed in their confronting faces with angular sockets, in come bination with a jewelry holding means inbe subsequently eluding a member of angular shape adapted PAUL EfHEoK.
